100 POINTS PLEASE HURRY Brianna solved a two-step equation, but she made a mistake along the way.
0.1x + 3 = 1.7
(-3) + 0.1x + 3 = 1.7 + (-3) Line 1
0.1x = -1.3 Line 2
(-0.1) + 0.1x = -1.3 + (-0.1) Line 3
x = -1.4 Line 4
What mistake did Brianna make?
On Line 1, Brianna should have subtracted 3 instead of adding -3.
On Line 1, Brianna violated the addition property of equality.
On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1.
On Line 3, Brianna violated the addition property of equality.
Answer:
3rd row
Step-by-step explanation:
there were multiple mistakes there ngl but out of the amswers i saw it should be that brianna should habe divided

which is bigger 7/10 or 13/16
Answer:13/16
Step-by-step explanation:trust me bro
Answer:
13/16
Step-by-step explanation:
So what we want to do here is find the smallest common denominator. I personally find 160 the easiest to work with.
7x16=112(numerator for 7/10)
10x16=160(denominator)
This gives us the fraction 112/160.
13x10=130
16x10=160
This gives us the fraction
130/160
Therefore 13/16 is bigger.

Bob and Cheryl are taking a road trip that is 188.60 miles. Bob drove 1/4 of the total distance
How many miles did Bob drive?
Answer: 47.15 miles.
Bob drove 47.15 miles.
To find how much Bob drove simply divide the total distance 188.60 miles by 4.
188.60/4 = 47.15
One winter day, the outside temperature, y, was never below −1°. The inside of a car was always warmer than the temperature outside by at least 4°. Which graph of a system of inequalities represents this scenario?
On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal to the y-axis at y = negative 1. Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 4) and (2, negative 2). Everything below and to the right of the line is shaded.

Answer:
The correct option is;
On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal to the y-axis at y = negative 1, Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 4) and (2, negative 2). Everything above and to the left of the line is shaded
Step-by-step explanation:
The inequality representing the first line is y ≥ -1
The inequality representing the second line is y > x + 4
Therefore, the first line is a solid horizontal line with the shaded region above the line
The second line is a line with a broken line with positive slope slope with the shaded region being above the line and to the left

NEED ANSWER ASAP-
What is the value of x?
Given:
The figure.
To find:
The value of x.
Solution:
In triangle HIJ, HJ is diameter of the circle.
[tex]\angle HIJ=90^\circ[/tex] [Thales's Theorem]
[tex]HI=IJ[/tex] [Given]
[tex]\angle IHJ=\angle IJH=x-42^\circ[/tex] [Base angles of isosceles triangles are equal]
Now,
[tex]\angle HIJ+\angle IJH+\angle IHJ=180^\circ[/tex] [Angle sum property]
[tex](90^\circ)+(x-42^\circ)+(x-42^\circ)=180^\circ[/tex]
[tex]2x+6^\circ=180^\circ[/tex]
[tex]2x=180^\circ-6^\circ[/tex]
[tex]2x=174^\circ[/tex]
Divide both sides by 2.
[tex]x=\dfrac{174^\circ}{2}[/tex]
[tex]x=87^\circ[/tex]
Therefore, the value of x is [tex]87^\circ[/tex].

Answer:
i got 34:34:112
Step-by-step explanation:
sorry im bad at explaining things but i added a picture
Answer:
34, 34, 112
Step-by-step explanation:
(6x+10)+(x + 17)+(4x-34) = 180
=> 6x+x+4x = 180 -27+34
=> 11x = 187
=> x = 17
6(17) + 10= 112
17+17 = 34
4(17) -34 = 68 - 34 = 34

Robert is a high school basketball player. In a particular game, he made some three point shots and some free throws (worth one point each). Robert made a total of 9 shots altogether and scored a total of 23 points. Write a system of equations that could be used to determine the number of three point shots Robert made and the number of free throws he made. Define the variables that you use to write the system.
Answer:
let t = number of three-point shots
let f = number of free throw shots
Step-by-step explanation:
t + f = 9 (he made a total of 9 shots altogether)
3t + 1f = 23 (number of shots multiplied by their point value)
substitution method: t = 9 - f
3(9 - f) + f = 23
27 - 3f + f = 23
-2f = -4
f = 2
find 't': t + 2 = 9
t = 7
Rewrite the following equation in slope-intercept form
y - 4 = 3(x + 2)

Mario is playing an online puzzle game. He has 50 points and earns 3 points for each puzzle he solves correctly. He will advance to the intermediate level if his score is over 80 points. Which inequality can Mario use to find how many more puzzles he must solve to advance to the intermediate level?
Answer:
y = 3x + 50
x = # of levels completed
Step-by-step explanation:
Answer:
The inequality 50 + 3x > 80 can be used by Mario to find how many more puzzles he must solve to advance to the intermediate level.
Step-by-step explanation:
Given that:
Points of Mario in online puzzle game = 50 points
Points earned for each puzzle solved correctly = 3 points
Points needed to advance to intermediate level = over 80 points
Let,
x be the number of puzzles needed to be solved by Mario to advance to next level.
Points Mario already have + Points for each puzzle * Number of puzzles > Points needed to advance
50 + 3x > 80
Hence,
The inequality 50 + 3x > 80 can be used by Mario to find how many more puzzles he must solve to advance to the intermediate level.
